Title: Switch/power drop unit for modular wiring system
Inventor: EWALD MICHAEL D
IPC: H02G3/18
Filed: 2002-07-11
Abstract: An assembly for connecting a pre-wired electrical device into a modular wiring system. The electrical device is mounted in a junction box having a knockout hole.  Device wiring connects the electrical device through the knockout hole to a connector plug.  Cable wiring connects a modular wiring system power tap connector to a connector socket.  The cable wiring runs through a flexible conduit sheath. A knockout connector is connected to the flexible conduit sheath. The connector plug connects to the connector socket. The major width of the connector plug/socket combination is less than the diameter of the knockout hole such that the connector plug/socket combination may be pushed into the junction box through the knockout hole. The knockout connector can then be attached to the junction box at the knockout hole. The power tap connector housing, flexible conduit sheath, knockout connector and junction box are all made of nonflammable materials.

Abstract: The invention relates to a screw connection comprising a seal ring (1), a connecting piece (10), and a union nut (11) for joining pipes, whereby the seal ring is designed as a cutting ring having one or more cutting edges (2, 3). Said cutting ring can be inserted into a boring of the connecting piece, said boring conically exiting a face, by screwing the union nut onto the connecting piece, and the exterior of the seal ring is provided with a ring reinforcement on the side of the nut. Said ring reinforcement forms a ring surface on the transition thereof to the narrow ring part. The ring surface produced by the reinforcing part of the cutting ring is provided with a slope to the pipe axis that ranges from 45 °° to 90 °°. When fully assembled, the axial length of the ring reinforcement is such that the transfer elements placed on the ring surface transfer their negative image or themselves onto the face of the connecting piece. The transfer elements have three-dimensionally shaped contours whose negative image can be transferred to the face of the connecting piece. In a manner similar to a die, the negative image is pressed into the face of the connecting piece by the pressing force exerted by the assembler.

Inventor: WU YAOKUN
IPC: E21D21/00
Filed: 2003-08-11
Abstract: A mine roof bolt assembly for use in a bolt hole includes a rebar having an externally threaded end and a nut or other suitable fastener which is configured to threadedly engage the threaded end of the rebar. Bores formed through the nut and rebar are configured for alignment when the nut is positioned on the rebar in a first or initial position. A pair of shear pins are inserted so as to locate partially within segments of the bore formed in the nut, as well as within the bore formed through the rebar. The pins have a sizing selected so as to maintain a spacing between the innermost pin ends which are proximate to each other. The spacing in between the inner ends of the pins is selected so that when the fastener is rotated relative to the rebar under a predetermined minimum torque, the pins fracture or shear at the junction between the nut and the rebar. The pin fragments within the rebar thus may move inwardly into the spacing towards each other so as not to interfere or otherwise wedge between the bolt and nut threads, as the nut is threaded onto the bolt.
